Flu or Cold Symptoms?

Reviewed by Carol DerSarkissian on November 11, 2020

When you wake up sneezing, coughing, and have that achy, feverish, can’t move a muscle feeling, how do you know whether you have cold symptoms or the flu?

It’s important to know the difference between flu and cold symptoms. A cold is a milder respiratory illness than the flu. While cold symptoms can make you feel bad for a few days, flu symptoms can make you feel quite ill for a few days to weeks. The flu can also result in serious health problems such as pneumonia and hospitalizations.

What are common cold symptoms?

Cold symptoms usually begin with a sore throat, which usually goes away after a day or two. Nasal symptoms, runny nose, and congestion follow, along with a cough by the fourth and fifth days. Fever is uncommon in adults, but a slight fever is possible. Children are more likely to have a fever with a cold.

With cold symptoms, the nose teems with watery nasal secretions for the first few days. Later, these become thicker and darker. Dark mucus is natural and does not usually mean you have developed a bacterial infection, such as a sinus infection.

Several hundred different viruses may cause your cold symptoms.
